ISDN Service
Primary Rate Interface (PRI)
The iDCS 500 supports Primary Rate Interface ISDN. PRI allows simultaneous data calls, calling
party and calling line identification, high speed call setup and disconnect are among the benefits of
ISDN calling. The 30+D configuration of ISDN allows call information to be delivered via the data
channel (the "D" of 30B+D) thus leaving the bearer channels (the "B" of 30B+D) available for single
use or combined use to provide a wider bandwidth for data and video.
Basic Rate Interface (BRI)
The BRI card supports trunk or station level Basic Rate Interface services (BRI). Trunk or station BRI
use is software programmable. BRI allows simultaneous data calls, called party and calling number
identification, high speed call setup and disconnect are among the benefits of ISDN calling. The
2B+D configuration of ISDN allows call information to be delivered via the data channel (the "D" of
2B+D) thus leaving the bearer channels (the "B" of 2B+D) available for single use or combined use to
provide a wider bandwidth for data and video.
Least Cost Routing
Least Cost Routing (LCR) is the ability to automatically select the most cost effective central office
route for the outside number dialed by any station. The iDCS 500 LCR program includes the
following features:
Option to use or not use LCR or a tenant basis
Programmable LCR access code
Digit analysis table 1000 entries each with ten digits for a iDCS-M and 2000 entries each with ten
digits for a iDCS-L system.
Routing by time of day and day of week (4 time bands per day)
Routing according to individual station class
Modify digits table 100 entries for a iDCS-M and 200 entries for a iDCS-L system
Flexible trunk group advance timer
Option to use or not use trunk group advance warning tones
Live System Programming
The system can be programmed from any display keyset or personal computer without interrupting
normal system operation. There are three levels of programming: technician, customer and station.
The technician level has access to all programs and can allow the customer access to system programs
as needed. Technician and customer access are controlled by different security passcodes.
Programming from a PC requires the PCMMC program.
Meet Me Page and Answer
After a user makes a Meet Me Page, the user may remain off-hook to allow the paged party to meet
the user for a private conversation.
Memory Protection
In the event that power is lost to the system, all customer data contained in memory is retained by
the use of a "super capacitor" for approximately 7 days. In addition, the PCMMC computer program
may be used to produce a backup copy of the customer data. Additionally, the Smart Media card
may be used to store the system database.
